Hopefully no one was enjoying an afternoon nap just now, as the ground shaking was enough to wake almost anyone up.

The earthquake that just shook the Lamorinda area and beyond registered an initial magnitude of 4.0, according to the United States Geological Society, which makes it the biggest earthquake in the area in quite some time.

The epicenter registered about 2 miles east of Berkeley, so it was almost directly under our Orinda readers.

An earthquake of this size typically does not result in any injuries or significant damage; however, any updates to the contrary will be reported at that time.
